I have read a lot of stackoverflow questions but none seems to be working for me. i am using math.round() to round off. this is the code:

class round{

    public static void main(String args[]){

    double a = 123.13698;

    double roundOff = Math.round(a*100)/100;

    System.out.println(roundOff);

}

}

the output i get is: 123 but i want it to be 123.14. i read that adding *100/100 will help but as you can see i didn't manage to get it to work.

it is absolutely essential for both input and output to be a double.

it would be great great help if you change the line 4 of the code above and post it.

Try:

String roundOffTo2DecPlaces(float val)

{

    return String.format("%.2f", val);

}
